I've got the Beolink handbook , it shows the Powerlink wiring layout and pin 6 is datalink and pin 7 is it's shield/ground . I've connected these but no display and am a bit reluctant to try other combinations without knowing what I doing . The pin layout is as below .
Pin 1 = grey = power up/down
Pin 2 = shield = ground
Pin 3 = brown =signal left channel
Pin 4 = yellow = loudspeaker relay
Pin 5 = green = signal right channel
Pin 6 = white = datalink
Pin 7 = shield = ground
Pin 8 = pink = overload
I connected pin 6 & 7 on the Beomaster4500 to the same pins on one of the Penta's and commanded CD thru the Bs3 , speaker came on but no display . The data information must be there but the Bs3 doesn't pass it thru , my thinking is to bypass the BS3 with this data .
